rially-assist in igniting the gases passing to pelled to rise above the fuel to escape through opening 33, the. stove casing necesv sarily becomes very hot, andthe heat therea fore is more widely distributed.

In the form of the invention illustrated in Fig. 2, the openings 11,. are only shown op'-' posits the chamber while on the inside I of the fire ot I form a series of grooves 20",

extending from the top to the bottom of said fire pot for the free passage of air when the 'fuel becomes packed. a

Referring to Figs. 3 to 5, I have shown a tapered'fire potstructure, similar to that shown in Fig. 1, exceptthat it is :inverted. When in operation the fuel will readilp; fall Y because of the widest part of the pot eing at the bottom. The drum 3 may be perforated when used in connection with the form of fire pot shown inFig. 4, and when the fire pot becomes red by the heat, the openings expose it and give the same pleasing eI'l'ect jas-wh'en the openings expose the fuel.

In connection with the structures previously described, I may employ an air heating chamber 60, having an opening 61,-and damper 62, ,shownin Fig. 4. From this chamber depends a tube 63, to supply heated air to the fire pot, while heated air mayalso be directed from the chamber through pipe or pipes 65, to heat remote rooms. .A damper 66, over tube 63, closes. it, when it is desired to utilize the heat for the rooms. While I have onlyshown this feature in Fig. 4-, it is to be understood it may be applied to the other structures shown in this specification. For instance the tube may be used as shown at 63 ,-in Fig. 1.

. What I claim is I. A stove comprising a tapered fire pot formed with a series of inside flanges and a series otoutside flanges and openings adjacent the flanges, a series of upwardly ex-- tending grooves being formed on the inside of the fire pot, the grooved portionof said fire pot being imperforate, a drum surrounding the fire pot and an exit flue above the fire pot.

2. A stove comprising a casing, a tapered fire pot formed with openings, standards supporting the fire pot, means for supplying air to the lower part of the fire pot, a partition extending downwardly within the fire pot to provide a flue, and formed near its upper end with an opening, a pivoted damper the opening, a pivoteddamper in the fine, a link connecting the two dampers, and an exit pipe communicating with the flue.

3. A stove comprising a casing, a tapered fire pot, adrum surrounding the fire pot and spacedfrom. the tapered portion thereof, a chamber adjacent the fire pot and colnmunieating therewith, means for supplying a-ir to the chamber, a partition depending toward the fire pot and formed with an open mg near its upper end and enlarged at its "lower end, dampers connected to" move in opening to the I 4; A' stove comprising a fire pot formed with a-series of openings, a chamber. coinmunicating with the openings, means for supplying air to the chamberQa partition formed near its upper end with'an opening, and enlarged at its lower end, and de-. pending to a point within the 'upper'end of the fire pot the space between the casing and the partition fol-min a flue, dampers for directing, the ro ucts of combustion through theopenmg or the flue, and means for supplying air to the fire pot.

5. In a stove, the combination with a casing, a perforated tapered fire pot supported in the casing, there being a space between the fire pot and easing, there being a cham-- ber formed in said space, said chamber communicating with the. fire pot through the perforations therein, a cover for the cham her, aidamper for regulating the admission of air to the chamber, a partition extending toward-the fire pot to provide a flue, and means operatively located in said partition and fine for directing the products of combustion directly to the bottom of'the flue orto the flue near the top of the casing.

6. In a stove, the combination with a casing formed with openings, a perforated tapered fire pot supported in'the casing and spaced therefrom, a chamber formed in the said air escaping to the atmosphere through the openings in; the casing, means for intro- 'ducing air downwardly, in the fire pot, a

partition extending within the fire potto provide a flue, and means for directing the products of combustion to the bottom of thefluc or to the flue near the top of the casing.

I -7. In a stove, the combination with 0. casing, a fire pot supported in and spaced from the casing, and formed with openings to communicate with the space, means for introducing air to said space, a flue on the. inside of the casing, said flue communicating at its lower end with the fire pot,-and formed.

eeeeee near its upper end with an opening, a damper to close said opening, a damper located in the flue, at a polnt above the fire pot and above the bottom of said flue, said damper when closed completely closing the flue to prevent the products of Combustion passing in the lower-open end thereof, one of said dampers being closed While the other is open, means connecting the dampers to cause them -to be simultaneously operated to direct the products of combustion from a point near the top of the fire pot or from a point near the top of the casing.

8. In a stove, the combination with a casing, a fire pot supported in and spaced from the casing and formed with openings to communicate with the space, means for introducing air to the space, a flue above the fire pot formed at its lower end with an opening at or near the upper end of the fire pot and formed with a second opening near the upper end of the casing, means including two connected dampers operatively mounted in said flue and constructed to direct the products of combustion from a point near th top of the fire pot to the flue through 1h opening near the bottom thereof or through the said second opening to the flue at a point near the top of the casing, one of said dampers being located some distance from the bottom of the flue and above the fire pot and when closed fits the flue closely to prevent the escape of the products of combustion below said dam ers.

In testimony whereot I have signed my name to this specification in the presence of two subscribing witnesses.
